What it is and where it lands
The Siemens 3VM9404-0JC23 is a circular conductor terminal, type TA2.4, sized for two cables in the 70 to 300 mm² range. It ships as a pack of four units and is listed as an accessory for the 3VM13 and 3VM14 molded-case circuit breaker families.
Compliance and regulatory fit
RoHS compliant since June 2012, and REACH Article 33 information is available on request. Export control is straightforward: AL N / ECCN EAR99, no special licensing required for most destinations.
What it connects to
Designed specifically for the 3VM13 and 3VM14 series breakers — this is the lug kit that lands the incoming or outgoing cables onto the breaker terminals. The 70–300 mm² range covers the larger conductor sizes typical of main feeders or high-current branch circuits in switchboards and panelboards.
